Application October .25; 1948, Serial No. 56,422

,The, invention relates to an automaton or manikin, namely a self-movingmachine which imitates life like motions.

An object of the invention is to provide an automaton having a movablehead, with means for turning the head from one side to theother andfortilting the same in alife like manner.

Another object of the present inventionis to provide an automaton havinga movable head and movable arms which are operated in timed relationwith each other in a life like manner, particularly to simulate the actof cobbling a, shoe. -Our invention relates to advertising mediumsanclhas for its object to provide a new and highly efficient meansforand method of attracting attention of traffic passing down a busy streetto the fact that cobbling or shoe rebuilding is being done.

:A further object is to provide an automaton which simulates the act ofnailing a work piece. A further object is to-provide a puppet shoe makerworking on a shoe with all appearances of driving a nail into the heelof the shoe.

The invention provides a miniature man giving all the movements of handsand arms and head of a shoemaker driving nails into a shoe, the hammerdriving'the nail, the hand traveling to the mouthv as thoughgettinganother nail and then down to the heel ofthe shoe where, when thehand again leaves the shoe a-nail is visible stick- 6 Claims. i(Cl.40-126) Figure 6 is a plan view of the cam for operating thehammer-operating arm. 1

Figure 10 is a plan view of Figure 9.

Figure 11 is a view of the base of the neck,

which rests on the ramp shown in Figure 9.

In the drawings we have shown our mechanism as a model of a man A,seated on a cobblers bench B, to which the cobblers tray C is attachedby mounting the entire'device .Ollifi/ base 5. One

arm 2 of the body is provided with a hammer .4

simulate the work of a cobbler. $1 is. raised to the mouth as thoughtaking a tack and the other arm 3 is provided with the hand iv showingthe fingers as though they were grasping a shoe nail. The hands areoperated to The left hand ,4

the hand 4 is raised from the heel of the shoe ing up from the heel ofthe shoe and which, nail is then struck by the hammer and driven downinto the shoe. p I Theclaims in this case are being limited to thenailing feature, while claims generic to this case and to co-pendingapplication Serial No. 101,522 g filed June 27,1949, for AUTOMATON arebeing-v made in the latter case, particularlywith regard to the headcam, the cam assembly and to cams pears and giving the positions, of thehands at two different positions of the operation.

Figure 2 is a rear elevation of Figure 1, parts cut away to show theoperating parts of thedevice. I I

Figure 3 is a section on line 3-3of Figure 2;

; Figure 4 is a perspective diagrammatic illustration of the variouscams, shafts, and operating parts of the invention.

Figures is a plan viewof theeam for operating the left arm.

a-nail N is shown ready to be .driven by the hammer. This nail N is thetop end of a rod which extends down through the heel and is raised andheld by friction until the hammer strikes it, being raised to theelevated position while the fingers of the hand 4 are in contact withthe heel, as shown in Figure 1. The head A is slightly raised andlowered while it is being partially rotated from side to side in such amanner that it gives all the appearances of a natural person working ona cobblers bench repairing shoes. Each time the hammer drives down itforces the nail down into the shoe heel and each time the right hand israised and the left hand lowered to simulate withthe device.

placing a nail the nail N is elevated to. the raised position so thatwhen the hand leaves the shoe heel it gives all the appearances ofhaving left a nail sticking in the heel ready for the hammer.

The operating mechanism for the device consists of a casing D in whichthe worm gear for driving the device is mounted and in which theoperating cams and races are all mounted and operated, the casing beingadapted to be completely enclosed and filled with oil to prevent wear onthe cams and their coasting rollers and arms. Transversely through thecase D there is a shaft S which carries all of the cam races and thedriving worm wheel W. The worm wheel W is driven by a worm drivendirectly by the motor M,

the shaft M extending down from the motor to the worm inside the gearboxing. The motor M is mounted on a bracket extension on the back sideof the casing D and the motor is mounted on an angle and provided with acooling fan F to direct air currents over the motor to keep it fromoverheating from constant running.

On the shaft S there is a cam 12, the perimeter 13 of which is formed toactuate the left arm in its desired motions by the connecting orcontacting roller l4, shaft [5 and pivot block Hi. The

pivot block I6 is provided to enable the builder to get the shaftperfectly placed by use of the set screw I! in the block IS. The end oftheshaft i5 is pivotally attached to the vertical rod 18 man. Anextended arm 21 connects the shaft 20 with the arm 3 and supports andoperates the arm. A counter weight .22 is attached to the shaft 29 toaid in raising the arm.

The nail N is mounted through the heel of the shoe l0 and is theupturned end of a rod 24 which operates in the slot 23 of the lastsupport 9 which supports the shoemakers shoe I0. The rod 24 extendsthrough the slot 25 in the seat B and is attached to the rod 25 which ispivoted through the back of the case D with the other end bent forwardat 28 carrying a roller 30 operating on the cam 29, which cam is alsomounted on the shaft S.

A cam 31 is mounted between the cams l2 and 29 and actuates the rightarm by a roller 33 operating over the two ramp or cam surfaces a and b.The longersurface a is to simulate the full hammer stroke, while theshortersurface b is to Having thus described oiii invention; we claim:

1'. An automaton comprising a replica of a shoe maker seated on a stool;a shoe placed between his knees; a movable right arm holding a hammer, amovable left arm holding the fingers in a position simulating holding anail; said shoe slidably holding said nail in the path of said hammerand in the path of said fingers of the left arm, a movable neck and headsimulating looking down and then around; and a multiplicity of cams, andconnecting arms to cause the movable parts of the body to be actuated bythe rotation of the cams, one-of said cams and connecting arms beingoperative to raise said nail to a position projecting above said shoe,and another of said cams and connecting arms being operative to lowersaid hammer into driving relation with said nail.

2. An automaton comprising a body having a movable arm carrying ahammer, a work piece for simulated nailing, a rod projecting upwardlythrough said work piece and slidable to one position with a free end ofthe rod in the path simulate the short stroke of the hammer when 7 justsetting the nail. This stroke is when the hand A is resting on theheeland appears or.

simulates the setting of the nail after which the hand is removed andthe hammer strikes the nail N, driving it down into the heel hole. Theroller 33 is on the end of a rod-3Q which is pivotally mounted in theblock 85 by the set screw 36. The end of the rod 34 is attached to theshaft 31' which extends up into the body of the man and the top end ofthe shaft 31 is attached tothe 'lever 38 which is mounted on thetransverse shaft 39 mounted across the body of the man. The end of theshaft 39 is bent forward and the arm 2 is formed thereon. a

The head A is operatedby a cam race plate 43 carrying a cam groove orrace 4| in one face thereof in which cam 42 is operated. This cam 42 ismounted on the rod 43 which is passed through the rear face of the caseD using the case as a bearing therefor and the other end is turned downat the'rod M which rod is attached'to a b10ck'45. 46 which is mountedthrough an arm 4'! on a vertical shaft 48. The top end of the shaft 48-is carried in an operating sleeve 50 and the top end of the sleeve 50is formed as a universal 5| to allow for the nodding motion imparted tothe each of said cam means comprising a radial type of said hammer andprojecting above said work piece and simulating a nail, said rod beingslidable to a lower position with said free end within said work piece,cam means for raising said rod to said first position, and other cammeans for operating said arm.

3. An automaton according to claim 2, said work piece having an aperturetherethrough for frictionally holding said rod in said first position,
